Title: Use, process and apparatus for electrolytically recovering metals from a metal ion solution
Inventor: KUEHN-VON BURGSDORFF JOCHEN W
IPC: C25C7/02
Filed: 1991-11-28
Abstract: ABSTRACT            A method and apparatus for electrolytically recovering a metal from a metal ion solution is provided. The solution is located in a first cell and an electrolyte is located in a second cell.  In the first cell, metal is deposited onto an electrically conductive endless belt which is rotated from the first cell where it acts as a cathode to the second cell where it acts as an anode.  In the second cell, the metal on the anode is dissolved in the electrolyte and then electrolytically deposited in high purity onto a cathode.

Title: Continuous reception of program channels by a mobile receiver unit
Inventor: GOEKEN JOHN D
IPC: H04B7/185
Filed: 1992-04-13
Abstract: CONTINUOUS RECEPTION OF PROGRAM CHANNELS BY A MOBILE RECEIVER UNIT                 Abstract of the Disclosure A system and process for continuous reception of information by a mobile receiver unit passing among a plurality of spaced transmitters with each transmitter configured to individually transmit  signals to the mobile receiver unit.   The mobile receiver unit has a pair of scanning receivers controlled by a switching control module.  The module causes one of the scanning receivers to lock onto signals transmitted from one of the transmitters while causing the second scanning receiver to scan signals transmitted by the transmitters in the reception range of the scanning receiver.  Once the strength of the signal locked onto by the first scanning receiver falls below a predetermined minimum signal strength, the second scanning receiver locks onto the best suited received signal and the first scanning receiver is caused to commence scanning,  the roles of  the scanning receivers thus being reversed.  The process continues, with the roles of the scanning receivers constantly being reversed, as the mobile receiver unit traverses the signals broadcast by the plurality of spaced transmitters.

Title: Synthetic peptides with immunomodulating activity and their preparation
Inventor: SANTIAGO CALVO ESTEBAN
IPC: A61K39/00

Abstract: ABSTRACT          There are described new immunomodulator peptides of the general formula R1-aa1-aa2-aa3-aa4-aa5-Pro-aa7-aa8-aa9-aa10-aa11-aa12-aa13-aa14-aa15-R2 in which R1 represents H, R2 represents OH, or else R1 and R2 represent each an amino acid residue or peptide chains, equal or different, containing from 2 to 10 amino acid resi-dues, in such a way that when R1=H and R2=OH, the formula represents a  pentadecapeptide in  which the N-terminal and C-terminal amino acids are respectively aa1 and aa15; aa2 is a Val, Leu, Ile, Ala, Lys or Gly residue, aa11 is a Glu or Asp residue; and the rest of the amino acid residues aa? different from aa2 and aa11 may be any of the 20 natural amino acids.        The incubation of these peptides with lymphomono-nuclear cells obtained from peripheral blood increases their cytotoxic activity towards K562 and Daudi cells used as tumour target cells. Proliferation of the lymphomononuclear cells is induced together with an increase in the number and proportion of CD14+, CD56+ and CD11b+ cells. These peptides are useful in  biotherapy of  cancer, and also as reagents to evaluate the cellular responsiveness of the immune system.

Title: Double tab locking joint and associated forming methods
Inventor: COX JIMMY L
IPC: B21D39/03
Filed: 1992-09-01
Abstract: The  scroll  wrap  portion  of  a  centrifugal  blower housing is joined to the opposite scroll side portions thereof using uniquely configured double tab locking joints spaced apart around the peripheries of the scroll side portions.  To form the joints, spaced series of tabs formed along the curved side edges of the scroll wrap are extended outwardly through corresponding peripheral slots in the scroll sides, and are brought into side-by-side adjacency with outwardly projecting tabs formed on the scroll sides at their peripheral slots. Supported series of forming tools positioned outwardly of the opposite scroll sides are forced inwardly against the side-by-side tab pairs in a manner tightly rolling them together to simultaneously form all of the double tab locking joints around both of the scroll  side  peripheries.    The  rolled  joints  mutually interlock  portions  of  each  of  the  scroll  sides  with adjacent  portions of  the  scroll  wrap  in  a  manner essentially preventing any appreciably relative movement between the scroll wrap and side portions at their joined areas.

Abstract: ABSTRACT OF THE DISCLOSURE     An anchor for use in association with a support structure, specifically metal tin pan decking, and an apparatus for installing the same.  The anchor comprises a V-shaped member having diverging arms; and a gripping projection disposed proximate the end of each arms.   The arms and projections are aligned in the same plane and the projections preferably extend inwardly and downwardly towards the apex of the V-shaped member.  The apparatus comprises supports mounted on a shaft, the supports being adapted to hold an anchor therein.  Levers, engagable with the supports at one end and a gearing mechanism at the other end, permit the user to release the anchor from the supports.  The shaft is extended to reach the U-shaped tracks of the tin pan decking and the projections are disposed on either side of the desired track.  The anchor is released from the supports so that the projections pierce the track.  The apparatus is then removed and reloaded with the next anchor to be installed.

Abstract: An improved method for linking images at program activation is provided by use of a symbol vector in a sharable code image. The symbol vector is automatically construted which the linker and operating system use to effect fast loo-kup of symbol values at program activation, thus providing fiexibility similar to that of link-time binding. For each silar-able image being constructed, the programmer provides a list of symbols which are to be made visible outside of the image. These symbols may be procedure names, data cells, absolute values, or any other valid use of a symbolic value. The order of this list must remain fixed from one image build to the next. From this list, the "symbol vector" is constructed (as by the linker) of the value of each of the identified symbols, and the symbol vector is associated with the sharable image. A symbol table is also associated with the sharable image, where each symbol has the value of its index in the symbol vector. When resolving references to other images, the linker does a symbolic lookup in the symbol table of the target im-age and obtains the index into t the target symbol vector. That index is bound into the calling image. Then, at program activation, the image activator uses the index bound into a calling image to obtain the current value of the symbol in the target image.
